Wabco 4460044020 ABS Electronic Control Unit 4S/4M 24V

Description

The Wabco 4460044020 is an ABS Electronic Control Unit (ECU) designed for 4S/4M vehicle series operating on a 24V system. This unit is a critical component of the vehicle's braking system, specifically the Anti-lock Braking System (ABS), and is responsible for preventing wheel lock-up during braking, enhancing vehicle stability and driver control. It features a robust design with an IP 30 protection class and an operating temperature range of -40°C to +75°C. Its dimensions are 41 x 135 x 178 mm. This ECU is an OE specification device that helps to ensure consistent and reliable braking performance, contributing to enhanced safety on the road.

Key Features & Benefits

This unit is really the brains behind your anti – lock braking system. It monitors wheel speed sensors – there’s one at each wheel – and it uses that information to control the brake pressure to each individual wheel. It’s constantly checking if any wheel is about to lock up during braking. If it senses that's happening, it rapidly pulses the brakes on that wheel, letting it keep rotating just enough to maintain steering control. It also handles a few diagnostic functions, letting you or a mechanic know if there's a problem within the ABS system itself. Think of it as the conductor of an orchestra, but instead of instruments, it’s managing your brakes. It doesn’t actually do the braking—your foot still does that—it just makes sure the braking is done safely and efficiently. It works with the brake master cylinder and the hydraulic lines to achieve that. It receives data, processes it incredibly quickly, and then tells the hydraulic modulator what to do. It’s all about precision control.

Symptoms, Risks & Replacements

It’s a big safety item, honestly. If this thing fails, you lose the anti – lock function. That means in a hard braking situation, especially on a slippery surface, your wheels can lock up. When that happens, you lose steering control. It's like trying to steer a sled that's already sliding—not ideal! While your regular brakes will still work, you don’t have that extra layer of protection and control ABS provides. You’ll notice if it’s failing because the ABS warning light on your dashboard will illuminate, or you might feel pulsing in the brake pedal during normal braking. We carry these at Fixparts Online, and getting it sorted out quickly is always a good idea, given what it does.
